Struthiola leptantha, another species commonly known as roemenaggie, is a shrub that grows to 1 m along the west coast from the Cape Peninsula to the Richtersveld. This specimen was photographed in Namaqualand south of Springbok during August.

The branches are slender and sometimes hairy. The leaves are opposite, narrowly elliptic to oblong and hairy when young. The flowers are cream coloured, occasionally reddish; scented at night. They grow stalkless in upper leaf axils in long spikes. The calyx tubes are silky and slender. At the flower mouth the four sepals are reflexed, the eight fleshy petals or petal scales are spreading among notable hairs. There are four stamens inside the tube. The anthers are oblong, the stigma feathery. Flowering happens during winter and to midspring.

The habitat of the plant is stony slopes in sandy soil (Manning, 2009; iSpot; JSTOR).
